Performing a reference run
The shutter actuator can move the blind/shutters into scene and
other directly controlled positions only if the positions have been
stored beforehand. For this purpose, every output must perform
a reference run.

Move the blinds/shutters to the upper limit-stop position.

Wait until the output relay and the limit switch are off.
The shutter actuator does not store the blind/shutter positions
permanently. After each failure and return of the mains, a new
reference run is performed.
Without reference run, the shutter actuator sets for each output
the internal flag ‚Invalid position‘ which can be read out.
Automatic running time detection: storing the running times
With the running time detection activated, the device can find
positions and scenes only if the running times have been stored
beforehand. The running times must be stored in undisturbed
conditions, i.e. without any control operations being performed
and in the absence of wind, snow and obstacles.
For 230 V drives only.
